Breaking The Time Barrier: Organ Care System Preserves Lungs Outside The Body

تمنح تقنية الرئة الجديدة الأمل للمرضى الذين ينتظرون

Two people are alive today because of new technology adopted by Gift of Life Michigan in January.

TransMedic lung oxygenation machineThe 67-year-old man and 40-year-old woman, both living in Minnesota, received new lungs thanks to a new organ care system that preserves lungs outside the body and extends the amount of time from surgical recovery to transplantation. The ترانس ميديكس system also reconditions marginally healthy lungs after they’re connected to the machine, making more lungs healthy enough to transplant. The result: More lungs available and improved quality of the organs for recipients.

Without this system, donated lungs must be transplanted within six hours. In these cases, transplants were successful after seven hours. One set of lungs was preserved for 23 hours.

قال إيان موج ، مدير خدمات الأعضاء في Gift of Life Michigan: "هذا مثال رائع لما يمكننا القيام به". "يمكننا تخصيص رئتين لتكساس وكاليفورنيا وولاية واشنطن - ليس هناك قيود على دراية بها."

Lungs that are healthy and need to go a short distance are cooled and transplanted within 6 or 8 hours. . With TransMedics, recovered lungs are viable for up to 24 hours.

قال الدكتور أبو العلا ، جراح الزراعة في ميشيغان ميديسن: "يمكننا السفر مع الرئتين لمسافات أطول". أجرى أول حالة ناجحة لشركة TransMedics في ميتشيغان. "إنها تقنية متطورة للحفاظ على الرئتين خارج الجسم ، وينبغي أن تساعد في تحسين معدل استخدام الأعضاء."

In 2021, 33 pairs of lungs in Michigan could not be recovered because of those time and geographic constraints. With this innovation, lungs from a donor in Hawaii were successfully transplanted in a patient in North Carolina, a journey of about 4,700 miles. . The company has regularly recorded successful transplants between donors and recipients who are a thousand miles apart.

قال بروس نيسيلي ، نائب رئيس العمليات السريرية في Gift of Life Michigan: "هذا يوسع بشكل كبير مجموعة المتلقين ، مما يسمح لنا بإنقاذ المزيد من الأرواح".

قالت Dorrie Dils ، الرئيس والمدير التنفيذي لشركة Gift of Life Michigan: "نحن متحمسون لجلب هذه التكنولوجيا الجديدة إلى ميشيغان". "هناك أكثر من 50 شخصًا ينتظرون رئة جديدة في ميتشيغان. هذا يعني المزيد من الأمل لهم ولآلاف الأشخاص الذين ينتظرون عضوًا منقذًا للحياة هنا في ولايتنا وخارجها.

وأضافت: "هذا التقدم التكنولوجي سيساعدنا على النجاح في مهمتنا المتمثلة في تكريم الحياة من خلال التبرع". "هدفنا النهائي هو رؤية يوم لا يموت فيه أحد أثناء انتظار عملية زرع منقذة للحياة. مع ظهور التكنولوجيا الجديدة على الإنترنت والتكيف معها ، نقترب أكثر من ذلك اليوم ".
